To all whom it may concern i Be it known that I, JOHN F. llos'r'rm, ,a citizen of the United States, residing at Argentine, in the county of Wyandotte and State of Kansas, have invented certain; new

and useful Improvements in RollerrBepring Cages, or which the following is a speoification. i

This invention relates to improveinehts in cages for roller bearings, and one object of the same is to produce a cage which will admit of easy assembling of the rollers in place, and thereafter retain the same in position. I 2

Another object is to provide a very simple construction adapted to be stamped cheaply from sheet material. 5'

With these and other objects in view which will appear as the description jprocoeds, my invention consists in certain novel and peculiar features of construction as hereinafter described and claimed; and in order that the same may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1, is a vertical section through a roller bearing embodying my improved cage, the section being taken along the line I --I of Fig. 3. Fig. 2;, is a perspective view of a portion of my cage. Fig. 3, is a side view, halt in section along theline Ill-III of Fig. 1, of a complete roller bearing, and Figs. 4: and 5 are sectional views-0f a modificd construction, taken along lines IVIV and V-V respectively in said figures.

Referring to said drawing, the inner bean ing for supporting the rollers 7 is inthc form of a conical Sleeve 3, while the outer bearing for the rollers is a collar 5, the inner surface of which is of the proper slope to conform to that of the adjacent contacting faces of the rollers.

My cage is for the purpose of holding the rollers in proper spaced relation between the bearings 5 and 7. The cage is stamped from sheet material to form two parallel portions of different length, which may be bent into annular form with the outwardly extending flanges 4. The annular portions 2 thus form rings of different diameters and are connected by a series of bars 6, and prol v jccting from one of the rings 2 opposite each bar 6 is a similar bar 8, the flange 4 of which ring is slitted, as at 10, in order to allow bar 8 to be folded flat against bar 6. The opposite ring 2 is alsoslitted as at 18 at op- Specification of Letters Patent.

positc'sidesof bar 6, in order that the lug 1.2 formed between the slits 18 may be folded over the free end of bar 8 and hold the latter in place. Said bar 8 is provided with one or more pairs of curved wings 16, extending from opposite sides of the bar, each set of wings between adjacent. bars 8 forming a pocket in which to fit one of the rollers 7, as shown clearly in Figs. 3 and 4:. I have illustrated each bafr 8 as provided with two pairs of these wings 16, with lugs 20 on the ad jacent bar 6, adapted to be folded around bar 8 between said pairs of Wings whereby to securely clamp each pair of bars 6 and 8,

together. It] is obvious, however, that it would *rve equally as Well to equip the bars 8 with said lugs 20 as to locate them on bars 6; and, further, I may employ only one pair of wings to each bar 8, which wings may be located centrally or otherwise thereon, in

which event I may rely on the lugs 12 alone to clamp the bars together. Again I may equip the inner bars 6- with one or more pairs of wings 16, as shown in Figs. 4c and 5, in which construction the cage will re-- tain the rollers in place therein independently of a y other means, since the rollers are suppor-cd against movement in any direction except about their axes.

In assembling the rollers, the cage may be held with its smaller ring 2 down, and the rollers inserted within the pockets, after which the sleeve 3, having the inner and outer ribs 5) and 11 may be placed within the cage, the wings 16 being suiiicicntly resilient to'spread slightly to allow the passage of rib 11,- then springing back when the sleeve is in position. The collar 5 may then befitted ovcfithe rollers. The double Wing construction of Figs. 4 and 5 has the advantage that it may be used with a sleeve I having no inner rib 11, so that the sleeve may be the last part assembled, and can be removed at any time to get at the rollers, the latter being held in place by the wings of the bars 6. l ,j j s It will 'be apparent that the outer cross bars 8 maybe formed integral .iwith either of the lrings 2, or the same may be constructed of twosectio'ns to each bar, one extending from each ring and mccting, when foldcd,.{at some point along the bar 6.

Another importantadvantage to be noted in connection with the double bar construction lies in the fact that by merely removing the collar 5, any one of the bars 8,bcing resilient, may be sprung outward and the underlying rollers removed without disturb-- tegrally connected by a series of cross bars,

a second series of cross bars formed integral WlillOllG of said rings. each cross bar of sald second series being folded about its point of connection with said last-named ring and upon one of the cross bars of said first serles, means rormed upon the other of said rings and engaging the free end of each folded cross bar to secure the latter-in its.

-folded position, and pocket forming wings extendingfrom one of said series of cross bars.

52. In a rollerbearing cage, two rings con nected by a series of cross bars, a second series of cross bars carried by one of said rings and folded upon the first series, means carried by each ess bar of one series for securing the correspoiuling cross bar of the other series llllCl'tiO,, and pocket-forming wings extending from the cross bars ofone of said series. 3. In a roller bearingcage, two rings connected by a series of cross bars, a second series-of cross bars carried by one of said rings and folded upon the first series, carried by each crossbar ofone series and folded around the corresponding cross bar of the other series, and pocket-formingwings extending from the cross bars of one of said series.

4. In a roller bearing cage, two rings connected by a series of cross bars, a second series of cross bars carried by one of said rings and folded upon the first series,'means carried by the other or said rings and engaging the free end of each folded cross bar to secure the same to the corresponding bar of the other series, wings extending from of said series.

5. In a roller bearing cage, two rings. connected by a series of cross bars, a second series of cross bars carried by one ofsaid rings and folded upon the first series, means carried by each cross bar of one series for securing the corresponding cross bar of the other series thereto, and outwardly diverging wings carried by each cross bar of the folded series, the wings between each pair of adjacent wing carrying bars forming a pocket to receive a roller.

6. In a roller bearing cage, two rings connected by a series of cross bars, a second series of cross bars carried by one of said rings and folded upon the outer side of the first series, means for securing said series together, and one or more pairs of outwardly diverging pocket-"forming wings carried by each cross bar of the outer series.

7. In a roller bearing cage, two rings connected by a series of cross bars, a second series o't cross bars carried by one of said. rings arid folded upon the outer side of the first series, means for securing said series together, and one or more pairs of inward y diverging pocket-forming wings carried by each cross bar of the inner series.

8. In a roller bearing cage, two rings con nected by a series of cross bars, a second series of cross bars carried by one of said rings and folded upon the outer side of the first series, means for securing said series together, one or more pairs of inwardly di- -\-erging pocket forming wings carried by each cross bar of the inner series, and one or more pairs of outwardly diverging pocketforming wings carried by each cross bar of the outer series;

In testhnony whereof, I atlix my signature, in the presence of two witnesses.
